At the time I...
At the time I purchased this lower assembly, there were no complete 9mm rifles to be found. I started out with a 9mm upper and tried to convert my .223 lower to accept the 9mm mags using a magazine block. It was finicky to say the least and I had to mess with it a lot and it was unreliable. This lower came available so I purchased it to go with the CMMG 9mm upper that I already had. There was an occasional issue ejecting the spent shells, I called CMMG customer support and they gave me a solution which worked. I would recommend it if you already have a 9mm upper, but I would rather purchase a complete rifle so that it is adjusted from the factory and functions properly.

Lower arrived quickly...
Lower arrived quickly and in good shape. Fit my Colt style upper receiver with no problems. Both Colt and Metalform magazines function well. Would buy another with out even thinking about it.
